Newton's Laws of Motion

What is Newton's First Law of Motion?

An object at rest stays at rest, and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

What is another name for Newton's First Law?

The Law of Inertia.

What is inertia?

The tendency of an object to resist changes in its state of motion.

What is Newton's Second Law of Motion?

The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.

Q: What is a free-body diagram (FBD)?

A: A diagram showing all the forces acting on a body.

What are Newton's laws of motion?

Newton's laws of motion are three fundamental laws describing the relationship between the forces acting on a body and its motion. They form the basis for classical mechanics.

How are Newton's laws of motion applied to pulley systems?

In pulley systems, Newton's laws are used to analyze the forces (Tension, Gravity) and accelerations of connected masses. Typically, free-body diagrams are used for each mass to apply F_{net} = ma to determine motion or equilibrium, considering the tension in the string and (if present) the mass of the pulley.
